FIG. 2 is a perspective view of a meter box including a navigation system mounted to the vehicle of FIG. 1; and
FIG. 3 is a diagram showing the receivable range of satellite radio waves.
 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be described in detail hereinbelow with reference to the accompanying drawings. FIG. 1 is a perspective view of an ATV 1 as a vehicle equipped with a GPS receiver according to an embodiment of the present invention. ATV 1 has a seat 4 situated between front wheels 2 and rear wheels 3 having balloon tires and a fuel tank 5 located in front of the seat 4. A steering handle 6 and a meter box 7 installed at the center of the steering handle 6, and a section in front of the steering handle 6 is covered with a front fender 8 are provided in front of the fuel tank 5. A front carrier 9 for mounting baggage is provided on the top of the front fender 8. On the rear wheel 3 side, there are provided a rear fender 10 and a rear carrier 11. An engine and a four wheel drive unit for transmitting the power of the engine to the front wheels 2 and the rear wheels 3 are arranged below the seat 4.
The GPS receiver and a GPS antenna 12 for a navigation system which will be described in detail hereinafter are installed in the meter box 7. Particularly, the GPS antenna 12 is arranged at the highest position of the meter box 7. That is, in ATV 1, as illustrated in the FIG. 1, the meter box 7 is situated at the highest position of the vehicle, and the GPS antenna 12 is located at the highest position of the meter box 7. This is aimed to receive satellite radio waves with high sensitivity. The meter box 7 is covered with a cover 13.
The satellite radio waves are mainly received by the GPS antenna 12 installed in the meter box 7. A second GPS antenna 14 may be mounted on the rear fender 10 or the like. This makes possible diversity reception that the satellite radio waves can be received better. It is recommended to mount the second GPS antenna 14 to the distal end of a pole 14 a set in the rear fender 10 so that radio waves can be received at a higher position. The GPS antenna 14 may be mounted to not only on the rear fender 10 but also any one of the fenders covering the four wheels.
FIG. 2 is an exploded perspective view of the meter box 7 when seen from the front of the vehicle. In FIG. 2, the meter box 7 has frames 16 fixed to the support member 15 of the steering handle 6, and an indicator 17 and a GPS unit 18 are held to the frames 16. The indicator 17 is arranged such that its screen is opposite to a driver so that he/she can easily see it. The GPS unit 18 is arranged before the indicator 17 in a forward direction of the vehicle, and the GPS antenna 12 is situated almost at the same height as the upper end of the indicator 17. The GPS unit 18 calculates position information based on satellite radio waves received by the GPS antenna 12 and the running distance and direction of the vehicle.
The indicator 17 has a display panel for displaying information on the driving states of ATV 1 such as the speed of the vehicle and the exchange time of engine oil and information on the location of the vehicle based on satellite radio waves received by the GPS unit 18. The position information can be displayed together with a map.
FIG. 3 is a diagram showing the receivable range of satellite radio waves. FIG. 3 is based on the assumption that baggage 19 is placed on the front carrier 9. Ranges where satellite radio waves to be received by the GPS antenna 12 are cut off by the baggage 19 and the driver D are denoted by C1 and C2, respectively. Since the GPS antenna 12 is installed at a high position of ATV 1 as can be understood from FIG. 1, the ranges of satellite radio waves cut off by the baggage 19 and the driver can be narrowed, and the satellite radio waves can be received well at a wide angle range (W).
Since the GPS unit 18 including the GPS antenna 12 is installed adjacent to the indicator 17, harnesses for interconnecting the GPS unit 18 and the indicator 17 can be shortened.
Since the GPS unit 18 including the GPS antenna 12 is installed adjacent to the indicator 17, the GPS unit 18 and the indicator 17 can be covered with the same cover 13, thereby making it possible to prevent a complicated front section of the vehicle that results from an increase in the number of covers.
Since the indicator is installed at a high position in ATV 1 in most cases, high-sensitivity reception is possible with the GPS unit 18 installed at a high position by arranging the GPS unit 18 and the indicator 17 adjacent to each other without making other modifications.
The present invention can be particularly advantageously applied to a four-wheeled ATV. It can be also applied to a two-wheeled or three-wheeled saddle-type vehicle.
As obvious from the above description, according to the present invention, since the GPS antenna is installed at a relatively high position of the vehicle, satellite radio waves can be received at a wide range and navigation information can be obtained with high accuracy.
According to the present invention, diversity reception is made possible with high sensitivity by using two GPS antennas installed at high positions of the vehicle.
According to the present invention, even when baggage is placed on carriers installed at the front and rear of the vehicle, as the baggage does not become too high when a front view is taken into consideration, satellite radio waves can be received well by the GPS antenna installed at a relatively high position of the vehicle.
According to the present invention, since the GPS unit and the indicator are arranged in proximity to each other and are covered with the same cover, harnesses for interconnecting the GPS unit and the indicator can be shortened, the production becomes easy and the appearance of the vehicle becomes good.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
